Forcing to boot from CD

I have a failing? drive and have another internal drive to install OS on. I swapped out the MB from the original (failing) 867. I put in the Install disk, select it for startup. I reboot, but apparently the startup disk isn't seen and it boots normally. I tried the Option key on boot, but only the original hardrive is seen...


Anyone know of a way around this as I assume the MB isn't recognizing the disk?


Thanks in advance,


rog

PowerMac, Mac OS X (10.4.11), MDD 1.25 Ghz

The install disk is for 866 DP MDD that came w/comp. I ended up swapping the MB due to multiple problems w/ 1.25 DP


I don't think it is reading it in the boot process. I replaced the drive about a yr ago with a 3rd party drive and am wondering if there is something I need to do get it to see the drive early in the boot process. The drive works because I can select the Install disk as the startup drive, however, when I reboot, it just boots off HD.


Holding down the C key does nothing and holding down the Option key only reveals the HD and not the Startup disk


I can certainly do the PRAM reset. I will try that tonite...


thx

I am running the 1.25 now. I reset the PMU last night and went thru the motions of PRAM. I did not hear the chime nor did the screen flash...


I have a newer brushed aluminum apple keyboard and was wondering if the MB is sensing it or does it need the supplied software to operate? I am suspect of this as the C key doesn't prompt either...


It's like all of the front end system check stuff doesn't cycle...

I am able to boot in safe mode, ran fsck -f and fixed a few minor things...


Didn't do anything for the booting from disk. Option key still only shows OS startup drive...I have an Apple Hardware disk I tried to boot from as well and they all get bypassed. I started getting the deathbox (force restart) when leaving the disk in the tray. I also have a USB backup drive that I had hooked up all the time. Tried ejecting via key command and Disk Utility...get the deathbox everytime...

Well, what is weird, is that on the original MB, I had 2 optical drives that became very flaky sometimes one mounting vs the other not or vice versa. When I replaced the MB, I got a new optical drive (1yr ago) and all is well...


CDs mount no problem albeit I did have some issues burning...


Is there a way to test? being the Hardware disk won't mount?


THanks for all of your help...


In the event this one does go by the grave, are the ATA drives compatible with the newer boxes (SATA) I hate to let those go...


Thanks again....
